Arabidopsis Unknown-eome

            [PUF Counts]
This page provides query and download options for the proteins of unknown functions (PUFs) from Arabidopsis.
Three methods were used for their prediction: (1) BLASTP searches (SW) against the proteins of known function (PKF) from
Swiss-Prot, (2) HMM searches (PF) against the Pfam domain database and (3) retrieval of the 'unknown' annotations from the
Gene Ontology system (GO, MF). More details and a summary table are provided on the PUF Count page. The unknown profiles
are defined as follows: U=PUF and K=PKF using the predicion methods in the order GO_SW_PF.
The 7th colum links to available experimental information in the Bioassay and Phenotype Database (BAP DB).
